This paper discusses the multipotency of cyst cells and proposes that understanding molecular circuits in cyst formation could enable engineering of desired stem cell culture phenotypes, but reports no new experimental outcomes.

This study found that upregulated miR-149 restricted hair follicle stem cell differentiation and hair growth by inhibiting the MAPK1/ERK2 pathway, which affects FGF2 and c-MYC expression.

In this study, transfection experiments showed that mutations in the K85 gene affect filament formation with K35, which may impact hair formation related to ectodermal dysplasia.

This study found that using a microwell array device to expand hair follicle stem cells in Matrigel significantly increased cell numbers and enhanced hair regeneration in mice.

This review synthesizes recent research on how Wnt signaling regulates skin, hair follicle, and nail regeneration, highlighting its compartment-specific roles and discussing targeted strategies for treating conditions like alopecia, chronic wounds, and skin cancer.

This review explores the role of FGF signaling in hair follicle development and highlights its potential as a new therapeutic target for hair loss, which could surpass existing treatments in terms of efficacy and safety.

This study found that hot water extract of Hydrangea serrata leaf and hydrangenol promoted hair growth by enhancing 5α-reductase inhibitory activity, stimulating dermal papilla cell growth, and exhibiting anti-inflammatory and anti-androgenic effects in cell cultures, mice, and human skin organoid models.

In this study, researchers developed WS Biotin, a new water-soluble form of biotin, and found that it significantly improves water solubility compared to free biotin and enhances hair-related keratin expression, gene activity for hair growth in vitro, while also reducing melanin content in skin cells.

This review discusses recent evidence on the Notch signaling pathway's role in regulating hair follicle development and stem cell differentiation, but provides no new research findings.

This review discusses the role of the Wnt/β-catenin pathway in hair follicle development and how natural products that activate this signaling could be used to treat hair loss, but it reports no new experimental results.

This study identified hair shaft progenitors in the matrix that regulate hair growth and pigmentation by creating a niche dependent on stem cell factor, implicating KROX20+ cells in these processes.

This study found that in naturally curved human scalp hairs, distinct arrangements of cell types on either side of the hair fiber contribute to its curvature.

This study found that nevoid basal cell carcinomas originate in the epidermis and upper hair follicles, resembling early nonnevoid basal cell carcinoma proliferations.

In this study, pilomatricoma, a benign skin tumor from hair follicle matrix cells, is highlighted as an important consideration when diagnosing painless, firm subcutaneous nodules, with accurate diagnosis relying on histopathological examination.

This study found that CRABP1, Nestin, and Ephrin B2 are expressed in both the tumor stroma and invasive front of skin adnexal tumors and basal cell carcinomas.

This study examined the subcutaneous structures in forehead creases using cadavers and observed that dense fibrous structures connecting the dermis to the frontalis muscle, as well as specific epidermal and dermal characteristics, may contribute to the formation of these creases.

This review discusses new developments in understanding the structure and properties of keratin fiber cell membrane complexes, without reporting new experimental results.

This study found that pilomatricomas exhibit co-expression of hair keratin hHa5 and HOXC13 in lower transitional cells, but lack LEF1 and β-catenin co-expression necessary for canonical Wnt signaling pathway-controlled cortical differentiation.

This study integrated single-cell RNA-seq data from four previous studies to create a comprehensive human corneal cell state meta-atlas, revealing novel marker genes, rare cell states, and distinct transcription factors, and offering a tool to enhance future cornea research.

This review discusses the molecular mechanisms involved in hair follicle development and regeneration, highlighting findings from mouse genetic studies, and reports no new experimental results.

This review discusses the role of corticotropin-releasing hormone in human skin, focusing on its regulation, receptors, and functions, and highlights parallels with the hypothalamo-pituitary-adrenal axis; it reports no new research findings.

This chapter reviews laboratory models used for studying alopecia therapies but provides no new experimental findings.

This review discusses Wnt signaling pathways in skin development and stem cell regulation, highlighting potential interactions with other pathways but reports no new findings.

This paper reviews the evolution of skin appendages and keratin-associated proteins among amniotes, proposing a model for their genetic divergence without new experimental results.

This study found that valproic acid promoted hair re-growth in C3H mice by activating the Wnt/β-catenin pathway, suggesting its potential as a treatment for alopecia.

This study found that cellular retinoic acid-binding proteins and fatty acid-binding proteins are dynamically expressed in skin development and respond differently to retinoic acid, β-catenin, and Notch signaling.

This study found that Runx3 deficiency in mice affects hair type and shape, suggesting it may regulate hair formation through interactions between dermal and epidermal layers.

This study's simulations suggest that biomechanical factors, like follicle geometry and tissue stiffness, are likely significant in hair fiber protrusion, providing a framework for future experimental validation.

This study found that the distribution of desmogleins is associated with specific types of keratinization and hair anchorage, as well as hypotrichosis.

This study found that knocking down the gene SFRP1 in human hair follicles ex vivo prolonged the hair growth phase and increased keratinocyte proliferation, suggesting potential as a therapeutic target for maintaining hair growth in male pattern baldness, while DKK1 knockdown showed no effect.
